A New York Times bestseller

The first sleep book by a leading scientific expert—Professor Matthew Walker, Director of UC Berkeley’s Sleep and Neuroimaging Lab—reveals his groundbreaking exploration of sleep, explaining how we will harness its transformative power to change our lives for the better.

Sleep is among the most important but least understood aspects of our life, wellness, and longevity. Until very recently, science had no answer to the question of why we sleep, or what good it served, or why we suffer such devastating health consequences when we don’t sleep. Compared to the other basic drives in life—eating, drinking, and reproducing—the purpose of sleep remained elusive.

An explosion of scientific discoveries in the last twenty years has shed new light on this fundamental aspect of our lives. Now, preeminent neuroscientist and sleep expert Matthew Walker gives us a new understanding of the vital importance of sleep and dreaming. Within the brain, sleep enriches our ability to learn, memorize, and make logical decisions. It recalibrates our emotions, restocks our immune system, fine-tunes our metabolism, and regulates our appetite. Dreaming mollifies painful memories and creates a virtual reality space in which the brain melds past and present knowledge to inspire creativity.

Walker answers important questions about sleep: how do caffeine and alcohol have an effect on sleep? What in reality happens right through REM sleep? Why do our sleep patterns change across a lifetime? How do common sleep aids have an effect on us and can they do long-term damage? Charting state-of-the-art scientific breakthroughs, and synthesizing decades of research and clinical practice, Walker explains how we will harness sleep to strengthen learning, mood, and energy levels; control hormones; prevent cancer, Alzheimer’s, and diabetes; slow the effects of aging; increase longevity; strengthen the education and lifespan of our children, and boost the efficiency, success, and productivity of our businesses. Clear-eyed, fascinating, and accessible, Why We Sleep is a an important and illuminating book.
